Is friendship supposed to feel like walking over the falls?

Brenda is afraid of heights, being in the dark, and dog poop. Then she meets daring, rule-breaking Maureen and realizes their friendship is a bit like walking a tightrope — exciting but dangerous. Maureen encourages Brenda to use fire escapes, sleep outside in a tent, and walk through strange backyards.

Their friendship strains when Maureen makes fun of Harvey, Brenda's special needs neighbour. It strains even further when Maureen borrows Gran's bracelet and lies about returning it. Suddenly, Brenda realizes she has to be as brave as The Great Blondin, the man who walked across the falls, to get it back.
